Shoe structure

ABSTRACT

A shoe includes an outsole having an end connected to a heel portion and a midsole located on the outsole. A support member supports on the underside of the midsole and has a side wall extending perpendicularly from a periphery of a rear end thereof. A connection piece has spikes which penetrate through the midsole and the support member, and are connected to a top of the heel portion. An insole is laminated on the midsole and a vamp is securely connected to a periphery of the outsole. The support member is made of composite fibers so as to bear the wearer&#39;s load and is not deformed because of its structural strength.

FIELD OF THE INVENTION

The present invention relates to a shoe structure, and moreparticularly, to a shoe having a midsole which located between theoutsole and the insole. The midsole is supported on a support memberwhich is made of composite material.

BACKGROUND OF THE INVENTION

A conventional shoe structure 10 is shown in FIGS. 1 and 2 and generallyincludes an outsole 12, a midsole 13, an insoe 13 and a heel portion 11.The outsole 12 has one end adhered to the heel portion 11 which has anextension 111 from a top thereof so as to laminate on a top of theoutsole 12. The midsole 13 and the insole 14 are respectively attachedto the top of the outsole 12. The extension 111 is generally made ofmetal so as to provide support of the load applied on the shank of theshoe between the heel portion 11 and the outsole 12 that contacts theground. Nevertheless, in order to reduce the total weight of the shoe,the extension 111 is made to be a thin plat which tends to be deformedby the load and the deformation of the extension 111 makes the shoe tobe uncomfortable. Some material for the extension 111 could get rustedwhich contaminates the appearance of the shoe.

The present invention intends to provide a shoe structure that has amidsole supported on a support member made of composite material and thesupport member has a side wall for providing better support for thefoot.

SUMMARY OF THE INVENTION

In accordance with one aspect of the present invention, there isprovided a shoe structure which comprises an outsole connected to a heelportion and a midsole is laminated on the outsole. The midsole issupported on a support member which is made of composite. A side wallextends perpendicularly from a periphery of a rear end of the supportmember. A connection piece has spikes which penetrate through themidsole and the support member so as to be connected to a top of theheel portion. An insole is laminated on the midsole and a vamp issecurely connected to a periphery of the outsole.

The present invention will become more obvious from the followingdescription when taken in connection with the accompanying drawingswhich show, for purposes of illustration only, a preferred embodiment inaccordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 3 and 4, the shoe structure of the present inventioncomprises an outsole 23 having a bent end which is connected to a heelportion 21 and a heel lift 24 is connected to an underside of the heelportion 21. A midsole 26 is disposed on the outsole 23 and a supportmember 27 supports on an underside of the midsole 26 and located betweenthe outsole 23 and the midsole 26. The support member is made ofcomposite fibers 27 and includes a side wall 271 extendingperpendicularly from a periphery of a rear end thereof. A connectionpiece 261 has spikes 262 which penetrate through the midsole 26 and thesupport member 27 so as to be connected to the top of the heel portion21. The midsole 26 and the support member 27 can be made as a one-piecemember which is light in weight and may bear large load on it so thatthe shoe is not deformed when the shoe is used for a period of time. Theside wall 271 of the support member 27 may extend to a plantar arch ofthe wear's foot so that it prevents object from penetrating the midsole26 and protects the wear's foot.

The support member 27 can be made of thermosetting plastic orthermo-plastic. The thermosetting plastic or thermo-plastic can be mixedwith other material when making the support member 27.

An insole 22 is laminated on the midsole 26 and a vamp 25 is securelyconnected to a periphery of the outsole 23.

The shoe is light and the support member 27 provides a good support sothat the shape of the shoe is maintained even if the shoe is used for along period of time. The side wall 271 enclose the foot heel of thewearer and provides comfortable wearing feature.

The composite fibers of the support member 27 may also be woven witheach other and include specific patterns, and the outsole 23 can be madeof transparent material so that the patterns can be seen via thetransparent outsole 23.

As shown in FIG. 5, the insole 22 on the midsole 26 is in flush with atop edge of the side wall 271 of the support member 27.

While we have shown and described the embodiment in accordance with thepresent invention, it should be clear to those skilled in the art thatfurther embodiments may be made without departing from the scope of thepresent invention.
